The contents of a topic:

Congenital Hypertrophic Pyloric

Stenosis

Impaired patency of the pyloric part of the stomach is a genetically determined malformation and results from hypertrophy and degeneration of the pyloric sphincter. Infantile hypertrophic pyloric stenosis (IHPS) is a common surgical condition encountered in early infancy, occurring in 2~3 per 1,000 live births. It is characterized by hypertrophy of the circular muscle, causing pyloric narrowing and elongation. The incidence of disease varies widely with geographic location, season and ethnic origin. Boys are affected four times more than girls.

There is evidence of a genetic predisposition to the development of this condition. Siblings of patients with IHPS are 15 times more likely to suffer the condition than children who have no family history of IHPS. The cause of hypertrophic circular muscle of pylorus is still obscure and various hypotheses have been advocated including abnormal peptidergic innervation, abnormality of nitrergic innervation, abnormalities of extracellular matrix proteins, abnormalities of smooth-muscle cells and abnormalities of intestinal hormones.

Clinical picture. The first manifestations of the disease usually appear from the end of the second or the beginning of the third week of life. Its main sign is projectile vomiting between feedings. The vomited material is congestive in character: its amount is greater than the dose of a single feeding and it contains curdled milk with a sour smell.

The child starts losing weight, signs of dehydration appear, and the baby urinates seldom while the stool is small in amount. In the acute form of the disease the signs develop rapidly and violently, so that the patient’s condition grows worse in a week.

The hemorrhagic syndrome may develop in severe cases as a consequence of intravascular coagulation of blood.

In the sub acute form, the signs progress gradually: the baby regurgitates and vomits at first once or twice and then more frequently as a result of which hypotrophy develops. No gross water-electrolyte disorders occur in this form.

On examination of the patient attention is focused on the degree of hypotrophy and exsiccosis, epigastric distention, and increased peristalsis of the stomach of an “hourglass” type. X-ray and endoscopic methods of examination are applied to make the exact diagnosis. The size of the stomach, the presence of fluid in a fasting stomach, the time of the first evacuation of the stomach, the condition of the pyloric anal, and the time of full evacuation of the stomach are studied during X-ray examination. A distended stomach filled with gas and with a fluid level is found during scout examination. Segmental peristalsis of the stomach and absence of primary evacuation into the duodenum are demonstrated 15-20 minutes after a contrast medium (5 per cent aqueous barium suspension in 50-70 ml of breast milk) is given; a constricted pyloric canal is seen on a lateral view. Examination of the patient in 3, 6, and 24 hours reveals retention of the contrast medium in the stomach.

Differential diagnosis is made with pylorospasm, the adrenogenital syndrome (Debre-Fibiger syndrome), and partial duodenal obstruction above the major duodenal papilla. It is based on the difference in the X-ray and endoscopic pictures, the time of appearance of the first symptoms of the disease, and the results of biochemical tests. In pylorospasm, evacuation of the contrast medium from the stomach is disturbed for more than 2-3 hours, and antispastic therapy produces a good effect.

The adrenogenital syndrome is characterized by an admixture of blood in the vomit, hyperkalaemia and hyponatraemia; evacuation of the stomach does not suffer. The appearance of symptoms from the first days of life and typical X-ray findings are specific of high intestinal obstruction. Fibrogastroduodenoscopy helps in the diagnosis.

Treatment. Pylorostenosis requires surgical treatment. The operation is preceded by preoperative management for correcting dehydration, alkalosis, and hypokalaemia. The operation is conducted under general anesthesia. Access to the pylorus is gained through a superomedian or transrectus incision or through a transverse incision in the superior abdominal quadrant.

The Fredet-Ramstedt operation is performed. The seromuscular coat of the pylorus is cut in the vascular zone and the cut edges of the muscle are drawn apart with an instrument until the mucous coat the pylorus prolapses into the wound for the whole distance of the incision. The thickness of the muscular coat on section ranges from 0, 5 to 1, 0 cm, whereas normally it is 0,1-0,16 cm thick.

The most responsible moment is division of the pylorus at its junction with the duodenum because the muscle is thinned out here and the overhanging mucosa may be injured. To check the intactness of the mucous membrane, the stomach is compressed and its contents moved towards the duodenum. This simple manipulation allows perforation to be recognized in time. If perforation is found, the defect is closed with one or two sutures. Should this prove difficult, the site of pyloromyotomy is sutures and a cut is made on the contralateral side.

As the result of the operation, the anatomical obstruction is removed and passage of the pylorus restored. Three hours after operation the child is given a drink of 10 per cent glucose solution, in another 4 hours 10 ml of drawn off breast milk is given at intervals of 2 hours for 10 feedings daily (no night feeding). In the following days the amount of milk is increased by 100 ml daily (by 10 ml for each feeding). From the 5th day, when the child already receives 50 ml of milk every 2 hours, its amount is increased to 70 ml and the interval between the feedings is prolonged to 3-3,5 hours, after which the common type of feeding is given.

The lack in proteins and fluids in the first postoperative days is made up parenteral by intravenous infusion of plasma , 10 per cent glucose solution , and Ringer-Locke solution. Micro enema is prescribed every 4 hours (15 ml of 10 cent glucose and 15 ml of Ringer-Locke solutions). The prognosis is favorable.

Congenital Intestinal Obstruction

Congenital intestinal obstruction is among the most common morbid conditions call for emergency surgery. It is encountered in children of any age, though most frequently in the neonatal period. It is caused by various malformations which can be conventionally separated into groups: (1) malformations of the intestinal tube; (2) malformations of the intestinal wall; (3) malrotation of the intestine; (4) defective development of other abdominal organs.

These malformations originate during organogenesis (the first 3-4 week of intrauterine development) when one of the processes of the formation of the intestinal wall and lumen and the growth and rotation of the intestine are distorted.

The digestive tube goes through a “solid” stage during its development, with the proliferating epithelium closing the intestinal lumen completely. The process of vacuolation which follows next terminates in the restoration of the lumen of the tube. In certain cases, however, the last phase is disturbed and the intestinal lumen remainsclosed. When recanalization is disturbed only in a small area the lumen is closed with a thin membrane (membranous atresia). An opening of various size forms in the membrane (membranous stenosis) in cases in which recanalization has already started. In closure of the lumen for a considerable distance, the atresia has the character of a fibrous strand. This form of atresia may result from deficient development of the corresponding branch of the mesenteric vessel. Atresia may be multiple (“sausage” form).

The malformations are encountered most frequently in the regions of “complex embryological processes”, namely, in the major duodenal papilla, at the junction of the duodenum and the jejunum, and in the distal segment of the ileum.

Delay of rotation in the different stages may result in various malformations which cause intestinal obstruction. When this happens in the first stage, the baby is born with incomplete rotation of the intestine. The midgut (stretching from the duodenum to the middle of the transverse colon) in this case remains fastened at one point, at the origin of the superior mesenteric artery. The loops of the small intestine are in the right half of the abdominal cavity, the caecum is in the epigastrium, under the liver or in the left hypochondria, the colon is on the left. This type of fixation creates the conditions for torsion about the root of the mesentery and the development of acute strangulation intestinal obstruction.

When the second stage of rotation is disturbed, the caecum located in the epigastrium is fastened by embryonic strands in front of the duodenum and compresses it.

Compression of the duodenum may be combined with torsion around the superior mesenteric artery, this is known as Ladd’s syndrome. Atypical position of the vermiform process together with the caecum makes the diagnosis of acute appendicitis in older children and even in adults difficult.

In disturbance of the third stage of rotation, fixation of the intestine changes which results in the formation of the defects in the mesentery and various pockets and recesses predisposing to strangulation of the intestinal loops.

Meconium ileus is a condition of peculiar origin, it results from congenital cystic fibrosis of the pancreas. Due to the deficient enzymatic activity of the gland, the meconium is abnormally viscous and blocks the lumen of the ileus.

All types of congenital intestinal obstruction are subdivided into high and low according to the level of the obstruction, into acute, chronic, and recurrent according to the course, and into complete and incomplete according to the extent of closure of the intestinal lumen.

The method of examination in cases of suspected congenital intestinal obstruction consists of the following moments:

1. history (the time of appearance of the symptoms and the dynamics of changes in them);

2. general condition (signs of exsiccosis and toxicities, degree of prematurity, combined maldevelopmental anomalies, manifestations of birth injury and infections);

3. examination of the abdomen (distension, asymmetry, Vaal's symptom, tenderness, peritoneal signs);

4. intubation of the stomach (determination of the amount and quality of the gastric contents);

5. rectal examination;

6. X-ray examination.

Differential diagnosis. High intestinal obstruction must be differentiated from pylorostenosis, pylorospasm, and the pseudo occlusion syndrome. In contrast to duodenal obstruction pylorostenosis occurs in later periods and is marked by vomiting, of curdled milk without admixtures of bile or green matter. Pylorostenosis has typical X-ray and endoscopic pictures. Pylorospasm is characterized by inconstancy of signs and good effect of spasmolytic therapy. The pseudo occlusion syndrome occurs characteristically in premature babies. The differential diagnosis is based on the X-ray picture (retention of evacuation of the contrast medium) and the efficacy of non-operative measures (neostigmine methylsulphate, siphon enemas, irrigation of the stomach).

Low intestinal obstruction is differentiated from dynamic obstruction. As distinct from congenital obstruction intestinal paresis develops more gradually in babies at the end of the first month of life and older who suffer from some disease (severe pneumonia otitis, intestinal infection, sepsis). Paresis is marked by uniform distension of the abdomen, absence of peristalsis, and by signs of severe toxicosis. X-ray examination reveals abnormally large amounts of gases in the intestine.

Treatment. Surgery is indicated in congenital intestinal obstruction. Preoperative management is an important stage; specific futures are determined by the type of the obstruction (high or low) the duration of disease, and the child’s age. The character of the operation depends on the anatomical variant of the malformation. Access is gained by median, transrectus or transverse laparotomy. The opened abdominal cavity is inspected, taking careful note of the presence and character of the exudate, the size and appearance of the intestinal loops, the size of the mesentery and whether it is attached normally.

In high obstruction, the intestine appears collapsed and only the duodenum and the initial portion of the jejunum are drastically distended above the obstruction. An atretic duodenum is often larger than the stomach, the pylorus is stretched out and outlined as a hardly noticeable groove (double-cavity reservoir). Low obstruction is characterized by drastically distended afferent intestinal loops whose diameter is 10-12 times that of the collapsed intestine.

With the location and anatomical variant of the malformation determined, the main stage of the operation is begun. Ladd’s syndrome is the most common cause of high congenital obstruction. After evagination of the intestine into the wound, it can be seen that it is twisted one to three times around the root of the mesentery. With the volvulus corrected, the caecum is usually found high in the left half of the abdominal cavity while the wide planar strand radiating towards it from the right lateral part of the abdomen compress the duodenum and cause its obstruction. Ladd's operation consists in correcting the volvulus and dividing the peritoneal strands; the caecum is transposed into the left half of the abdomen, calculating on its taking the normal position in the right lower abdominal quadrant in 6 to 12 months. In other cases with incompleted torsion surgery consists in removing t-he obstruction by a simpler method (division of the strands, closure of the defect in the mesentery, correction of the volvulus).

The operation of choice in atresia of the duodenum and its compression by annular pancreas or an aberrant vessel is posterocolonic anterior duodenojejunostomy. Duodeno-duodenoanastomosis is established in high duodenal atresia (above the level of the major duodenal papilla); some cases with membranous atresia and stenosis are managed by duodenotomy and subsequent excision of the membrane and transverse closure of the intestine with sutures.

In atresia of the jejunum and ileum, the atresic intestine is resected together with the distended blind end and 5-7 cm of the collapsed distal segment, which is functionally deficient, is also removed. The continuity of the intestine is restored by side-to-side or end-to-end anastomosis established by single-row Halsted's sutures applied with atraumatic needles. The anastomosis should be at least 2.0-2.5 cm wide.

In atresia of the terminal segment of the ileum, the abnormal part of the intestine is resected and the end of the small intestine is anastomosed with the side of the colon.

Meconium ileus is managed by Mikulicz's operation consisting in extra-abdominal resection of the intestinal segment filled with the abnormally viscid meconium and establishment of double ileostomy which is closed in 3 or 4 weeks. Typical resection of the small intestine is recently used in the management of meconium ileus. Pancreatin is administered through the enterostomy in the postoperative period to liquefy the meconium.

The results of treatment depend on timely diagnosis and the combination of developmental anomalies in the child. Complications in the form of intestinal necrosis (in volvulus), perforation and peritonitis (in low intestinal obstruction), and irreversible disorders of homeostasis develop in late diagnosis.

Hirschsprung’s Disease

Hirschsprung’s disease (HD) is characterized by an absence of ganglion cells in the distal bowel and extending proximally for varying distances. The absence of ganglion cells has been attributed to failure of migration of neural crest cells. The pathophysiology of Hirschsprung’s disease is not fully understood. There is no clear explanation for the occurrence of spastic or tonically contracted aganglionic segment of bowel.

The aganglionosis is confined to recto sigmoid in 75% of patients, sigmoid, splenic flexure or transverse colon in 17% and total colon along with a short segment of terminal ileum in 8%. The incidence of HD is estimated to be 1 in 5000 live births.

The disease is more common in boys with a male-to-female ratio of 4:1.

Clinic and diagnostics of the disease of Hirschsprung

The earliest and basic clinical symptoms - absence of an independent stool (a chronic constipation). This symptom is mostly expressed already at newborn. Initial displays of constipations, their subsequent character in the greater degree are caused by length aganglionic segment, character of feeding, the equalizer opportunities of intestines. Sometimes regular incomplete stool of intestines result in condensation and congestion of the stool mass as stool stones in the distal department.

Constant symptom of disease of Hirschsprung - meteoric which also appears in the first weeks of life. The chronic delay of stool and gases causes expansion by sygma and other departments of the colon, that already in the first months causes increase of the sizes and change of a configuration of a stomach: navel is smoothed or it turn out and it is located below, than usually, the stomach is asymmetric. By palpation on a place of the protrusion the huge overflow with excrements is precisely determined. As a rule, palpation provokes amplification peristalsis and then it is appreciable as on a stomach " shaft " go.

At many children secondary changes as anemia are marked, hypotrophy. In the started cases there is a deformation of a breast: the costal arch is developed, the angle of it comes nearer to blunt.

At a long delay of a stool owing to an intoxication or intestinal impassability vomiting can arise. More often it is observed at new-born and nursing-babes. Vomiting is accompanied sometimes with pains in a stomach. Their occurrence should guard especially for a combination it frequently is an attribute of terrible complications of impassability or a peritonitis owing to punching a thick intestinum.

Conditionally symptoms can be divided into three groups:

1) early (a constipation, meteoric, increase of a circle of a stomach); 2) late (an anemia, hypotrophy, stool stones, deformation of a breast; 3) symptoms complication (vomiting, pains in a stomach, paradoxical diarrheas etc.).

Compensated stage

Symptoms of the first group are characteristic. The good leaving and conservative treatment promote regular daily stool of intestines rather long time. The general condition and physical development of the child practically do not suffer. Steady indemnification concerns to 1-st degree. Unstable indemnification when the slightest infringement of a mode recommended the doctor results in deterioration of a condition (stool constipation, loss of appetite etc.) concerns to 2-nd degree.

Sub compensated stage is transitive from indemnification to decompensated and on the contrary. In the first case disease proceeds as the compensated stage, but the general condition of the child slowly more often, but is progressively worsened. Alongside with symptoms of the first group there are also symptoms of the second group. In the second case disease, having begun with decompensated stages, with the appropriate medical help subsequently proceeds much more easy.

Decompensated stage

Depending on dominant semiology is possible to allocate first and second (chronic) its degrees. Sharp decompensation process right after births the phenomena of full low intestinal impassability. Quickly accrue. In some cases conservative actions (cleaning and siphon enema) allow to stop sharp decompensated. However stool seldom it happens full, the phenomena of impassability are recedive (chronic decompensation). In the latter case mark a combination of symptoms of the first, second and third groups.

Diagnostics. The diagnosis of HD is usually based on clinical history, radiological studies, anorectal manometry and in particular on histological examination of the rectal wall biopsy specimens. The diagnosis of HD is confirmed on examination of rectal biopsy specimens. The introduction of histochemical staining technique for the detection of acetylcholinestrase activity in suction rectal biopsy has resulted in a reliable and simple method for the diagnosis of HD. Full thickness rectal biopsy is rarely indicated for the diagnosis of HD.Once the diagnosis of HD has been confirmed by rectal biopsy examination, the infant should be prepared for surgery.

Radiodiagnosis in most cases has crucial importance, most informative is irrigoscopy with introduction of a baric suspension. Authentic (pathognomonic) symptom of disease - presence of the narrowed zone in distal departments of a thick intestinum with funnelled transition in suprastenotic expansion. Sometimes it is possible to find out rough plical in the expanded sites. Especially well it comes to light at rectosygmoid localization’s aganglionic segment. Also it is necessary to consider relative narrowing, i.e. a parity aganglionic zones and an overlying department. Radiodiagnosis at new-born is rather complicated. Therefore it is necessary to take into account a triad of symptoms: early constipations, a swelling of a stomach, presence on the roentgenogram of the narrowed zone with transition in suprastenotic expansion.

To additional methods of examination concern functional diagnostics and histochemical diagnostics.

Functional diagnostics includes: 1) all time control of the rectal pressure in rest and at any reduction of the sphincter; 2) examination of motor function of a rectum, internal and external sphincters; 3) electromyography of the internal and external sphincters; 4) reflexometry of the cough, anal and rectal reflexes. Paramount diagnostic criteria of disease of are return recto anal brake reflex (at a fast stretching of a rectum instead of a relaxation there is a reduction internal sphincter) and raised rectal pressure.

Histochemical diagnostics is based on qualitative definition of activity tissue acetylcholinestrase (ACE) or quantitative - sukcinatdegidrogenase. The first technique now is most distributed. Make superficial biopsy of the mucous membrane of a straight line and sygma and reveal increase of activity ACE on parasympatic nervous fibres of an own plate and muscles mucous. Results of reaction estimate as follows:

Negative - in actually muscular layer of a mucous membrane small amount ACE - positive fibres, in a mucous membrane of them is not present;

Poorly positive - in actually muscular layer of a mucous membrane small amount ACE- positive fibres, in a mucous membrane seldom located fibres;

Positive - ACE - in actually muscular layer of a mucous membrane it is more than positive fibres, in mucous they are traced precisely, their amount is significant;

Sharply positive - in actually muscular layer of a mucous membrane plenty ACE-of positive fibres which will penetrate in mucous, forming a rich network between glandulars.

Differential diagnostics should be carried out with meconium fuse, a stenosis of a terminal department of a rectum, functional impassability of intestines at new-born, a syndrome megacolon not clear ethiology, habitual constipations, endocrine infringements, hypovitaminosis B1, non-specific ulcer colitis, dysentery.

Treatment only surgical. Three variants of treatment are tactically possible: 1) fast and radical intervention; 2) imposing time colostomy and a delay of radical operation; 3) conservative treatment of a constipation until the expediency of operation will be established. Conservative treatment and colostomy apply as the important stages of preoperative preparation.

To conservative treatment concern: diet which relax intestinum, gymnastics and TFE. Cleaning and siphon enemes which are the basic means.

Radical surgical treatment of disease of Hirschsprung consists in a resection aganglionic segment of a thick intestinum whenever possible closer to anal. Now apply the following techniques:

Operation Svenson-Chiatt-Isacov is abdominal-perinea rectosygmoid-ectomy. Will mobilize distal department of a thick intestinum, making the resection aganglionic zone together with a part of the expanded intestinum, impose a straight line anastomosis between reduced colon and the rectum crossed on 4-5sm. higher anal than an aperture and temporarily imaginative through back pass.

Operation of Rebind consists in introabdominal resections aganglionic zones and anastomosis impose below transitive plicae of the perineum.

Operation Duamel-Bairov - retro rectal trans anal bringing colon descending, with creation between a back wall of a straight line and the end reduced colon seamless anastomosis with the help crusied clips.

Operation Soave-Lenushkin - endorectal bringing colon descending without initial anastomosis, demucousing rectal piece of the parts of intestinum and then reduce on perinea its free end, leaving it outside back pass as freely hanging of the stump. Last cut in 10-15 days after adhesion a serose-muscular case of a rectum with reduced colon.

Operation Soave-Bole - endorectal bringing colon descending with imposing initial colorectal anastomosis on distance 1 sm. from the anal apertures.

Even after successfully carried out operation of the patient requires a complex of actions for rehabilitation. Conditionally the program of rehabilitation can be divided into two stages:

The first - readaptation, the second – rehabilitation.

Readaptation follows rectum operative intervention and consists of the following measures: common-health (a diet, vitamins, the fermental and bacterial preparations stimulating means), metabolic therapies, local actions. Duration of this stage not less 2-3 month.

Rehabilitation has the main problem final strengthening of skills independent of the defecation, normalization of function of holding device of rectum. This stage includes common-health measures, physiotherapy exercises, physiotherapy, sanatorium treatment. Duration of the second stage from several months about several years.
